question

Since you mention the client doesn’t trigger any errors, where you get the error message? In addition, you can try to add some breakpoints in your code to check if the receipt has been obtained in production environment. If the receipt can be obtained, are there any messages returned by the validate IOS Receipt API?

Sorry about the late response; I try to capture the event from Data Explorer, but is not working. I got stuck on "Loading."


Anyway: for every error from the client side, we send a custom event to Playfab, so we are able to track every problem on the client side.

As you see in our code, at the end of ValidateIOSReceipt we have a Debug.LogError to track validation failure.

But the effect is that on sandbox environment always is working fine, but in production we don't see any error related to that and we don't see the purchase tracking.

Only we got are that message "OnPlayfabValidationError" 400 Bad Request on play stream. I suppose is something generate by the system.

I cannot put a breakpoint in production environment. What I do is publish in production a new version with some kind of log and sent it to playfab before the validation. But it is a very long process, I need to pass throw Apple for review and tooks days.

Any change to have more insight about the cause of that "bad request"? It seems to me like a bad call to an API for some parameters maybe?

Did you see something wrong with our code? Have you some links to examples of Unity IAP and validation to try to compare solutions?

thanks
